Would this be overkill for a 29 gallon freshwater tank? If so, is there another model by Eheim I should look at getting?

With regards to biological/mechanical this filter is ideal for this size of aquarium, in short you can not over filter a established aquarium. It is very dependant on the occupants of the tank, a shoal of Neons would not create the same biological load as a pair of Oscars, thus this filter is adaptably for any biological load.

Yes probably. I have a 75 gallon freshwater planted tank and I have an Eheim filter. In the two of the three baskets of filter media I have this. This is a fabulous product as it keeps the good bacteria in the aquarium on the media. I just rinse it out every time I clean the tank with lukewarm water and reuse it until it gets the color of a dark caramel. Hope this helps and good luck.

This what I used for my quarantine Tank for new comers. Fish seemed to like it. Real quiet. I do agree with capslock and it might not be enough to clear all dead spots in tank if you have alot of decor. A friend of mine has two of these with the random flow caps on top of them, His tank is a taller 30g though. If you need more info share what kind of tank your setting up too, this will help define what flowrates are needed, ie. is saltwater, reeftank, freshwater?

I would go with 150 more filtration for your tank, I have regular 29 gallon tank and I have Marineland 200 filter works great. 2 month went by and water still clear and all water tests pass.

Honestly I have a 50 gallon with the 306 on it and I'm not very happy. I'm trying different things so I can't condemn the 306 just yet. What I can tell you is a have a 75 gallon for 2 pretty much full size Red Eared Sliders with a condo so the tank is full and I have about 20 Goldfish with the Fluval FX6 and the water is crystal clear! Have it on for almost 2 months and haven't even need to do a water change yet. So worth the money. And if at this point I wish I would have gotten the FX6 for my 50. My advise go with the FX6 --so worth the extra money!

They only recommend the 3152 for tanks up to 50 gals. so the 3155 might be a better option for you.

I have this in 110 gallons and it is way overkill, mine has goldfish and they are supermessy as well, still keeps it fresh and clear!

I think the 306 would be perfect for a 40 gal tank. It has adjustable flow via a valve at the connections. I have a 206 on my 29 gal running full flow with community fish. Not excessive current. The flow rate is higher on the 306 by about 50%, but your tank is roughly 40% larger than mine. Plus it has more media capacity to increase filtration for those dirty cichlids.

I don't recommend 30 Gallons tank. I bought this for 10 gallon tank. It was not enough.And I found a problem. Connection is weak.(from light parts to AC adaptor)

Likely much too big. Try a turkey master. Works well on tanks up to 10 gallons.

I purchased a fluval 306 for my 60gal tank & the water flow is strong. Depending on how big your next tank will be 206 is suitable up to 45gal, 306 up to 70gal, & the 406 is up to 100gal. You can always adjust the aquastop valve to regulate your water flow without harming the motor, but not sure it may still be too strong of a water flow for a 30 gallon tank. (my fluval filters values are always fully open)

Maybe. The Hydor is fairly large and 1050 gph in a 40 gallon freshwater tank may be too much...I have a reef tank and more flow is typically better. My Hydor gave me a few problems by stalling and required frequent cleaning, but again, this may be due to the saltwater. I switched to the Tunze 6045, which is a lot quieter and hasn't stalled once. They are more expensive but there is the 6025 that's reasonable and is 740gph. I'd recommend doing more research for freshwater tanks, but I'd think that 740gph would be good for a 40 gallon tank.

Yes, I'm running it in mine. I have a plexi and I think it does a great job. I also have this on my 20 gallon puffer tank. You'll love it. Much better than the other makers.

You will not get maximum growth, but it certainly did make a difference on my 29 gallon tank. You can use 2 of them, and alternate starting them and refilling them by 2 weeks. I soon replaced the fermentation tank with a 3 liter bottle, but used the diffuser, which is not a bad design due to it's simplicity. You could also get a powered diffuser to use with the system that certainly would be enough for your 29.

I purchased Gulfstream Tropical Mag-Float for my wife. She uses it every week when I change the water in our 29 gallon aquarium. It does a great job for its size. Would recommend for your tank.

I am running this for a 15 gallon system and it isn't anywhere near enough. I just ordered a new one myself. You have at least 170 gallons. You can never have too much air, go to the full blown big commercial one and you won't be sorry that you did. You might spend 80 to $100 dollars now, but trust me, if you have that many tanks already, you will ultimately need it anyways.

It won't fit your tank. My recommendation would be to get a canister filter. You will have more control over filtration, water flow and currents. Canister filters also work better and are more efficient than a hang on back.
